   sätze 17   und   j ! S angeordnet, welche zwischen sich   einen ringförmigen Satz von Leit-   schaufeln   19 besitzen und den Druck des aus der Kammer 5 durch eine oder mehrere passende Expansionsdüsen 11 darauf geleiteten Dampfes aufnehmen. Durch diese Anordnung wird die Energie des Dampfes vor seinem Eintritt in die ringförmige Kammer 9 der Lauftrommel ausgenutzt. 



   Die Anzahl der Düsen 11, welche von der Eintrittskammer 5 zum ersten Lauf-   schanfelsatz führen,   kann eine beliebige sein und zwischen einer Düse und einem sich vollstandig über den Umfang des Rades erstreckenden Satz schwanken. 



   Aus der ringförmigen Kammer 9 strömt der Dampf durch Düsen 12 in die Leitund Lanfschaufein   13, 14, 15, 16.   Die Geschwindigkeit des Dampfes wird zunächst in den Lanfschaufeln 17, 18 ausgenutzt. Beim Austritt aus den Düsen 12 äussert der Dampf einen   Itückdruck,   während der Rest seiner Geschwindigkeit in den anschliessendon   Schaufelsätzen   ausgenutzt wird. 



   In den Fig. 6 und 7 ist eine weitere Ausführungsform gezeigt, bei welcher die die Wirkung   hervorbringenden Merkmate   im wesentlichen dieselben sind, wie in den Fig. 4 und 5, nur dass die   dosen 111   mit ihrer Achse wagerecht statt senkrecht und die Laufschaufeln   l11   und 181 und die'Leitschaufeln 191 infolgedessen so angeordnet sind, dass sie radial von dem Rade ausgehen. Wenngleich die anderen Teile in ihrer Form etwas von dem beschriebenen abweichen, so besitzen sie doch dieselbe allgemeine Anordnung und Wirkungsweise, welche daher aus der bisherigen Beschreibung   verständlich   ist. 



   PATENT-ANSPRÜCHE : 
1. Dampfturbine mit Druckstufen und einer oder mehreren   Geschwindigkeitsstufen   in   jfdor Druckstufe, dadurch gekennzeichnet,   dass am Anfange jeder Druckstufe die   Kxpansionsd(lüsen auf   der Lauf trommel angeordnet sind, zu dem Zwecke, den   Druckabfall     durch Reaktion   auszunutzen.

 EMI2.2
   sentences 17 and j! S arranged, which have an annular set of guide vanes 19 between them and absorb the pressure of the steam conducted thereon from the chamber 5 through one or more suitable expansion nozzles 11. By this arrangement, the energy of the steam is used before it enters the annular chamber 9 of the drum.



   The number of nozzles 11 which lead from the inlet chamber 5 to the first set of treads can be any number and can vary between a nozzle and a set that extends completely over the circumference of the wheel.



   From the annular chamber 9, the steam flows through nozzles 12 into the guide and landing blades 13, 14, 15, 16. The speed of the steam is first used in the landing blades 17, 18. When the steam emerges from the nozzles 12, it exerts a back pressure, while the rest of its speed is used in the subsequent sets of blades.



   A further embodiment is shown in FIGS. 6 and 7, in which the features producing the effect are essentially the same as in FIGS. 4 and 5, only that the cans 111 with their axis horizontal instead of vertical and the blades 11 and 181 and the guide vanes 191 are consequently arranged so that they extend radially from the wheel. Although the shape of the other parts differs somewhat from that described, they still have the same general arrangement and mode of operation, which can therefore be understood from the description above.
